Even as an analyst--as I've been off and on--I didn't necessarily do a ton of breakouts. I'd watch the keynotes, whether in-person or streaming, and then it was hallway track, meetings, and usually some sort of separate analyst/media activity.
There are probably counter-examples, but I'm not sure where I'd go if I were, say, an enthusiastic amateur physics or chemistry enthusiast of some sort that would be especially accessible.
